Light Bleeding At 14 Weeks

I started spotting on Saturday, and it hasn't stopped as of today, Tuesday. It hasn't gotten worse, and my Doc told me as long as I wasn't going through a pad every hr that I was okay. I am just scared and looking for other people who have had this. This is my 3rd, and last preg, and I didn't have this with the other two. Other than the light bleeding, I feel fine. Any1 else have this, or is having this? Did the baby go on to be healthy. Any advice, please, or kinds words :-)
